Umm Hani' narrated that she entered upon the Prophet (ﷺ) on the day of the Conquest of Makkah, when he was performing Ghusl - while a garment was screening him - from a vessel in which were traces of dough. She said:
He prayed Ad-Duha - but I do not know how many Rak'ahs he prayed - after he finished Ghusl.'"
